bors 4b8f431995 Auto merge of #103214 - Nilstrieb:set-theory, r=petrochenkov ... Use Set instead of Vec in transitive_relation Helps with #103195. It doesn't fix the underlying quadraticness but it makes it _a lot_ faster to an extent where even doubling the amount of nested references still takes less than two seconds (50s on nightly). I want to see whether this causes regressions (because the vec was usually quite small) or improvements (as lookup for bigger sets is now much faster) in real code.		2022-10-19 13:53:06 +00:00
